100
The word(s) that IMF stands for.
What is intermolecular forces?
100

The strongest IMF that gives substances a very high melting and boiling point.

What is hydrogen bonding?

100
Linear shape bond angle.
What is 180 degrees?
100

Trigonal Pyramidal # of lone pairs on the central atom.

What is 1 lone pair?

100
What VSEPR stands for.
What is Valence Shell Electron Pair Repulsion?
200
The definition for intermolecular forces.
What is the attraction between different molecules?
200
When molecules have a high melting and boiling point, that means their IMF's are stronger or weaker.
What is stronger?
200

What's the definition of "steric number"

What is the number of bonds and lone pairs attached to the central atom?

200

Tetrahedral steric number.

What is 4?

200
The two different types of pair repulsion of VSEPR's.
What is lone electron pairs and bonded electron pairs?
300

What IMF describes how nonpolar molecules interact?

What is London Dispersion Forces?

300

Dispersion forces are stronger in molecules with a larger or smaller mass?

What is larger mass?

300

VSEPR shape of a molecule with two lone pairs and two bonds on the central atom?

What is bent or angular?

300
How to know if a bond is trigonal pyramidal.
What is if there are three bonds with one lone pair?
300

The process to determining if a molecule is polar.

What is using the electronegativity values to determine if there's polar or non-polar bonds. And then what is determine whether the molecule is symmetrical or not?

400

What intermolecular forces that involve molecules that have uneven distributions of electrons?

What is dipole-dipole and Hydrogen bonding?

400

Hydrogen bonds are strong due to these bonds within a molecule.

What is H-O, H-N, and H-F?

400
How to know if a bond is bent.
What is if there are two bonds with 1 or 2 lone pairs?
400
How to know if a bond is tetrahedral.
What is if there are four bond with no lone pairs?
400

This helps to identify 3D molecular shape.

What is VSEPR?

500

The 3 basic types of intermolecular forces are.

What is (London) dispersion, dipole-dipole, hydrogen bond (not really a bond)?

500

List the IMFs from weakest to the strongest.

What is London dispersion, dipole-dipole, hydrogen bonding?

500

The most common linear and bent shape molecule/substance (one example for each shape).

What is CO2 (linear) and H2O (bent)?

500

The polarity of all trigonal pyramidal molecules AND the polarity of most tetrahedral molecules?

What is polar (trigonal pyramidal) and nonpolar (tetrahedral)?

500

Definition of a polar molecule.
